Dear Wolfgang,
thanks for the kind response. As a starting point, I would need to focus on
a scalar field, hence a finite element space for scalar values would be
sufficient, but obviously the mid-long term goal is to employ vector-value
finite element as well. I will try to have a look to the
Hello everyone,
I'm writing this post because I would need help to build a "particular"
finite element space. Let us suppose to have a scalar field in 2D. I want
to consider a family of basis functions along the horizontal direction
(e.g. basis functions based on Legendre polynomials) and a
periodic bcs in a matrix-free
framework for CUDA.
Thanks in advance
Best regards,
Giuseppe

Yes, I’m inside a clean directory. The output of mpicxx is “/opt/cray/pe/craype/2.7.10/bin/CC”, which is the same that I used to install all the other versions. The cmake version is 3.17.0. Best Giuseppe Orlando Da: Bruno TurcksinInviato: giovedì 20 luglio 2023 17:47A: dealii

Dear Bruno,
thanks for the suggestion. I tried to follow it, but I still the get same

Hello everyone,
I'm writing this post because I'm having some issues to compile the latest
release. I would need a version which supports CUDA and MPI being
CUDA-aware. Hence, I installed Kokkos using the flags
-DKokkos_ENABLE_CUDA=ON and -DKokkos_ENABLE_CUDA_LAMBDA=ON. Then, I tried

Here, you can find the two codes. 'SBR_GPU' is the one that arrives up to
the end, whereas 'SBR_GPU_WRONG' is the one that stops with the error
described above once I call 'output_results'. If the code is too long and
can be helpful, I could try to reduce it avoiding ParameterHandler and

I'm writing this post to ask some help for a CUDA code. I have implemented
a matrix-based CUDA coda for the so-called solid body rotation, namely a

I am writing this post to ask a curiosity about the MatrixFree
infrastructure. Is it possible to employ it for solving PDEs on surface

Indeed, looking at the documentation of the reinit function, it seems that

Dear Bruno,thanks for the kind response. I will certainly have a look to the files that you suggested me about the CUDAWrappers::SparseMatrix (and also the other tests included therein). Just as curiosity (if I am not inappropriate and you can answer me): are these new GPU facilities with Kokkos
Hello everyone,
I am writing this post to ask a couple of questions about the CUDA
facilities in deal.II, after a look on step-64 tutorial.

defined. Am I

interested in organizing a mini-symposium on “Computational Fluid Dynamics

the developers. Please, let me know if this can be of interest for you.

Good morning everyone,
I would have a question about the computation of integrals. Suppose I have
a rectangular domain, is it there any way to compute the integral of a
certain function over different heights (not only on the bottom or top
boundary)?

Good morning everyone,
I would have a question about the creation of a triangulation. Is it
possible to use the 'FunctionManifold' class to create a boundary described
by an analytical function? If so, how can I attach this manifold and

Dear Deal.II community,
I'm currently working on DG formulation for Euler equations with implicit
time-stepping, trying to combine in some sense the two approaches of ste-33
and step-67. I'm wondering if there is a way to employ automatic
differentiation in the matrix-free approach; I think
